摘　　要：区域参考框架是实现高精度区域大地形变观测和滑坡灾害长期监测的基础设施。结合活动地块的划分和长期的GNSS观测结果,笔者将我国大陆和海域初步划分为7个“刚性骨架地块”,简称“刚性地块”,拟建立覆盖我国陆海全域的区域参考框架系列:东北、华北、华南、西北、青藏、川滇及南海参考框架。本文介绍了从全球参考框架(IGS14)到区域参考框架的坐标转换方法,并例举了华北参考框架(NChina20)和华南参考框架(SChina20)在滑坡长期监测和滑坡初动自动识别领域的应用。Regional reference frames are the critical geodetic infrastructure for realizing high-accuracy crustal deformation and long-term landslide monitoring.According to the published results in active tectonic-block zonation and long-term GNSS observations,the authors divide China into seven“rigid-frame blocks”(or“rigid blocks”)and intend to establish the stable regional reference frame series covering the entire land and sea areas of China:Northeast,North,South,Northwest,Qinghai-Tibet,Sichuan-Yunnan,and South China Sea reference frames.This article introduces the method for realizing the coordinate transformation from the global reference frame(IGS14)to regional reference frames and exemplifies the applications of the North China Reference Frame(NChina20)and the South China Reference Frame(SChina20)in long-term landslide monitoring and initial slide automatic detection.
